COTTON-Proxima MACHINE.

1 'Application fusa August 31, 1926; kserial No. 132,746.

My invention has reference to an improvement 1n cotton picking machines and more particularly to an improvement in the beater theconstruction of the beater section of acotton picking machine, as shown Vin my prior United States Patent No. 1,073,785, issued to me ySepteicnber 23, 1913, cotton picking machine, whereby, I increase the capacity of the machine for cleaning motes, dust or other `foreign substances from the cotton, this increased cleaning capacity being about one third more than has heretofore been done.

My invention consi-sts in the peculiar and novel construction of the beater section of a i cotton picking machine, said beater section having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a vertical` longitudinal sectional view r'through the beater section of a cotton picking machine, said beater section being provided with my improvements.

Figure 2 is a bottom planview of the mote and trash receiving receptacle with the center portion broken. away and showing portions of the. machine sides in section.

Figure 3 is an enlarged detail4 transverse sectional view of my improved double grid bar. n f

Figure 4 is an enlarged detail horizontal sectional View, taken on line 4, 4,' of Figure 1, showing the means for securing themote and trash receiving receptacle to the grid bar support and looking in the direction of the arrow c. g

Figure 5 is a top plan sectional view of one side portion of themachine, taken online '5, 5, of Figure 1 and lookingdownin the direction of the arrow a. l Y

Figure 6 is a top plan sectional view similar to Figure 5 .of the other side portion of themachine. A i K Figure 7 is asectional view taken on line 7, 7 of Figure 1 and looking in the direction of the arrow Z), and f Figure V8 is a perspective view of part of `the perforated top plate, showing in detail the construction of one of the perforations or holes `in the top of the plate.

In the drawings 1 indicates the beater section of a cotton picking machine, the rest of the machine being broken away, 2, 2, portions of the side frames of the machine, 3, 3, the

usual drawing in rolls, 11, 4, the beater arms on the shaft 5, 6, 6, the grid bar frames and 7, 7, the usual crossv grid bars. The drawing in rolls 3, 3, and the beater shaft 5 are rotatably supported at each end in bearings, not shown,

and are drivenfrom the power mechanism, not shown, of the machine.

In place of the usual first single gridbar 7 I insert a double grid bar 8, as shown in Figures 1, 5 and 6, This double grid bar 8 is constructed of two grid `bars, 9 and 10. The grid bar 9 has inaddition to the usual con-k struction a screw threaded hole 11 and the grid bar 10 has in addition to the usual construction a vertical slot 12 andthe grid bar 10 is adjustably secured to the grid bar 9 by a screw 13 which extends through the slot 12 and screws intothe screw-threaded hole 11, as shown in Figure 3. This construction is repeated a number of times lengthwise of the grid bars. By this construction of the first grid bar, the cotton cleaning action of the first grid bar is accentuated or reduced, as required, by adjusting the grid bar 1-0 on the grid bar 9, Y

Each of the grid bar frames 6, 6, have, in addition to their usual construction for holding the ends of the grid bars, a flat end plate 14' formed integral with the grid bar frames .6, 6, and each is constructed to have a curved top edge and ribs 15, 15, in which are sheet metal plate grooves 16, 16. These ribs 15, 15,

with the grooves 16,`16, tl1en extend down- 'of the oppositely disposed ribs 15, 15. terminate in a hook shaped bearing 21 through which is a screw ,22; A flat sheet metal door l23 forms the bottom of the mote and trash re- 'ceptacle 2 0,iit is l,secured to a3 rod 24 the ends of which enter the yhook shaped bearings 21,-`

lll() lll) 2l, where they are held in vplace by the screws 22, 22, thereby hinging the door 23 to the mote and trash receptacle 20. Coiled springs 25, 25, on the rod 24 and engagingwiththe door 23 and the ribs 15, 15, holds the door 23 in the required position under spring tension. Fitted to the curved top edge is a perforated sheet metal top plate 26, which ext-ends over the entire top of the mote and trash receptacle 20. Just beyond the further side of 'the mote and trash receptacle 20, the perforated top plat-e 2G is bent downwards at an angle and forms a perforated top plate portion 27 which contacts with a cotton carrier plate 28 forming a part of the machine, as shown in Figure l. That portion of the topplate 26 edges 32, 32, which terminate into a curved edge portion 33. lVhere the straight angular edges 32, 32, and the curved edge 33 join are formed small upwardly bent tets 34, 34, as shown in Figure 8. These perforations or holes 29, 29, are positioned, relativelyV to the forward movement of the cotton, as shown in Figures 5 and G. The perforated topplate portion 27 is perforated with round holes 35, 35, as shown in Figure 7. The holes 29, 2 9, and 35, 35, are approximately the same size in area.

In the operation of the cotton picking machine the cotton goes through the machine in the direction of the arrows CZ, d, as shown. in Figures 1, 5 Vand 6. The operation of the several elements of my invention on thecotton, as the cotton passes through the beater section, is as follows. The twin or double grid bar 8 acts to remove a predetermined amount of foreign substances fromthe cotton and the usual grid bars 7, 7, Vwork in the usual-way as heretofore. The small upwardly extending tets 34, 34, at the holes 29, 29, in the top plate 26,` operate to remove foreign substances from the cotton, such foreign substances falling through the perforations or holes 29, 29, into the mote and trash receptacle 20, and-the suction` of the usual fan, vnot shown, draws air from below through the perforations or holes 35, 35, in the top plate extending portion 27, thereby facilitating the movement of the cotton through the machine. The motes, trash and other foreign substances falling into the mote and trash receptacle 20,. collect at the bottom on the now closed door 23. As the foreign substances collect on the door 23and` increase in weight, the door 23 gradually opens against the tension of the springs 25, 25, until a predetermined weight is obtained on the door 23, when the door 23 stays in this partly open position and the foreign sub$4 form, in effect, `a Vpackingwhich prevents the air suction through the machine from sticking the foreign substances from the receptacle "back into the cotton and as the air in the 'receptacle is now in a static or state of equilibrium` the foreign substances as they are removed from-the cotton, will now fall readily through the perforations or holes 29, 29, into the receptacle 20. y

I do not confine myself tothe construction shown `as this could be modified to accomplish the same result.

Having thus described my invention I claim as new l. In the beater section of cotton picking machine a curved sheet metal perforated plate forming the top of a mote and trash receptacle, each perforation having a straight edge merging into rounded corners which merge into straight angular edges which in I turn merge into a curved edge and upwardly extending tets at the curved edge, for the purpose as described. v

2. In the beater section of a cotton picking machine` a curved sheet metal perforated plate forming the top of amote and-trash receptacle, each perforation having a. straight edge merging into rounded corners which the'plate, the perforations being in the formr of round holes, for the purpose 4as described. 3. A twin grid bar for the beater section of a cotton picking machine, said twin grid bar consisting of. two grid bars facing each other, one grid bar being shorter than the other, the twin grid bar taking the` place of a single grid bar andmeans for adjustably securing the short grid bar to the other grid bar, .for the purpose as described.

4 4. In a cotton picking machine having a frame, a series of grid bars, a trash receptacle, a curved perforated plate over the trash receptacle of a grid bar bracket supporting the ends of the series of grid bars, said grid bar bracket having an `end exteiision which forms one endof a trash receptacle and also forms the support of one end of a curved perforated plate, said grid bar bracket being formed integral and secured to the frame of the machine, for the purpose as described.

In testimony whereof, I have signed my name to this specification.
